This social protection strategy how to transfer the child for home schooling been used both to promote social development and on humanitarian grounds. 1 Within a span of 10 years conditional cash transfer programmes have become the social intervention of choice in Latin America, which has set examples in this respect for other developing regions. The BFP is the world’s largest conditional cash transfer programme.
Some studies have examined the effects of the BFP on poverty and inequity,7 food expenditure,8,9 education and health service uptake8 and food security. 10,11 Most of these publications were recently reviewed. Since 2005 the Brazilian government has promoted periodic surveys known as Health and Nutrition Days to estimate the prevalence of anthropometric deficits in children up to the age of 5 years using the window of opportunity offered by National Immunization Days. 12 This strategy saves time and money because the immunization activities guarantee countrywide mobilization and the personnel, health facilities and equipment necessary to conduct the surveys. The objective of this study is to identify potential associations between enrolment in the BFP and the anthropometric indicators height for age, weight for age and weight for height in children under 5 years of age.
2006, population-based probabilistic samples of children less than 5 years of age were selected. Details of data collection and quality control procedures were reported elsewhere. 14 In short, local teams of five people were trained to collect data during National Immunization Days. Missing or incomplete data for any of the independent variables under study led to the loss of 2.
For the statistical analysis based on logistic regression, height for age, weight for age and weight for height were the dependent variables. 00 SD, according to WHO recommendations. The Health and Nutrition Day protocols were approved by the ethics committees of the National School of Public Health and the National Amazonian Research Institute. Children’s guardians were informed about the survey and signed informed consent forms. Anthropometric results were revealed to them immediately and severe cases of underweight were referred to the primary-health-care service.
